A rapid turn-on dual functional rhodamine B probe for aluminum (III) and copper (II) that can be utilised as a molecular logic gate and in water analysis

The new sensor, R34 was prepared from the reaction of rhodamine B hydrazide and 3,4-dihydroxybenzaldehyde, and it was characterised by spectroscopic techniques and single crystal X-ray diffraction. Sensor R34 can detect Al3+/Cu2+ through colorimetric and fluorometric methods in MeCN solution, which...
